HOT-WATER BOILER.

Specification of Letters Patent.

Patented Dec. 10, 1907.

Application led October 10| 1905. Serial No. 282146.

To all whom it may concern:

Be it known that I, HARVEY WILSON, a citizen of the United States, residing at Brooklyn, in the county of Cuyahoga and State of Ohio, have invented a new and useful Improvement in a IrIo'tNVater Boiler, of which the following is a speciiication.

The object of this invention is an inexpensive hot water boiler which can be readil taken care of by one man, and which will be economical of fuel.

The invention consists of the novel features of construction, hereinafter described, pointed out in the claims and shown in the accompanying drawings, in which,

Figure 1 is a perspective view of the boiler. Fig. 2 is a horizontal section through the upper part of the boiler. Fig. 3 is a detail showing a section of a fire grate. Fig. 4 is a section on the line 4 4 of Fig. 5. Fig. 5 is a section on the line 5 5 of Fig. 4. Fig. 6 is a section on the irregular line 6 6 of Fig. 4. Fig. 7 is a horizontal section on the line 7 and 7a of Fig. 6.

In these drawings, 1 represents the brick work and 2 the smoke flue, of the boiler. In the front of the brick or stone work are arranged doors 3, to provide means for cleaning out the upper part of the boiler, a fuel door 4, a clinker door 5, and an ash box and draft door 6. The boiler proper comprises the ash pin 7 and a plurality of grate bars 8. The fire grate is formed in sections 8a and each section is independently pivoted in the sides 9 of the ash box 7 by means of suitable pivot pins. Depending hangers 10, are connected to these pins on one side and carry pivot pins 11 which are connected by a bar 12. The bar 13, is connected to the forward pin 11, and extends through the front of the Wall l and is connected to a lever 14, by means of which all of the grate sections are shaken, simultaneously.

Above the fire grate 8, is a iire box 15, which is inclosed by rear and side water legs 16, which communicate with a horizontally arranged water space or chamber 17 immediately above the fire box 15. A flue 18 passes centrally through the rear portion of the chamber 17 and communicates at its lower end with the iire box 15, and at its upper end with a secondary combustion chamy ber 19.

ward the rear of the boiler, than the middle casing. By means of this construction, a zigzag passage is formed in the combustion chamber 19.

The Water jacket 23 is formed in the upper rear portion of the fire box 15, and beneath the waterchamber 17, and a water coil 24, is arranged in the upper portion of the fire box and in advance of the water jacket 23 and the coil is fed by a suitable supply pipe 25. The water legs 16, .are fed by suitable supply pipes 26.

It will be obvious, that the products of combustion passing through the iiue 18, will circulate between the casings 20 and thence pass out through an opening 27 to the smoke iiue 2. To further aid the circulation of water, in the 'water leg 16, the water jacket 23 communicates at its ends with said water le s.

-gHaving thus fully described. my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a boiler, a fire box, a combustion chamber arranged above the fire box, .a water chamber arranged horizontally between the fire box and the combustion chamber, a iiue passing through the said water chamber and affording communication between the iire box and the combustion chamber, rear and side depending water legs having free communication with the water chamber and the side legs having communication with each other, a plurality of casings spaced apart, and arranged in the combustion chamber, nipples connecting the casings with the Water chamber, and hot water pipes leading upwardly from said casings.

2. In a hot Water boiler a iire box, a water chamber above the iire box, depending water legs having communication with the water short of the front and extending further tochamber, a Water jacket arranged in the upper portion of the fire box and extending transversely across the box and opening at each end into' one of said Water legs, a Water coil arranged in the upper portion of the 'fire box beneath the -Water chamber and in ad- Vance of the Water jacket, and independent means for supplying Water to tbe Water llegs W.
